Unpacking Standards-Education

Unpacking Standards Template

For the identified standard address each of the following prompts.

Solve linear equations and inequalities with rational number coefficients, including those whose solutions require expanding expressions using the distributive property and collecting like terms.

Solve linear equations in one variable.

Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x=a, a=a, or a=b results (where a and b are different numbers). (8.EE.7).

Student-Friendly Format

Unpacking Standards-Education

How might you display the standard for your students?

The student will: demonstrate an understanding of how to solve linear equations in one variable with one solution, infinitely many solutions, or no solution by using the distributive property and collecting like terms to solve for the given variable.

Appropriate Parts

Knowledge and Skill Objectives

How you might explain the standard, and its parts, to a colleague?

Remember to identify each objective as either a knowledge objective or a skill objective, and to present the objectives in the appropriate teaching sequence if the sequence is of consequence. You must justify your sequence decision.

Analyze expressions looking for the distributive property and like terms. (Knowledge)

Formulate expressions from word problems and distinguish their equivalent expressions. (Skill)

Solve the equations created by the expressions. (Skill)

Unpacking Standards-Education

Use the distributive property and collecting like terms to solve a multistep linear equation. (Skill)

Sequence Justification

This sequence begins with simple concept knowledge of the distributive property and collecting like terms, then teaches students how to solve a linear equation in one variable using these skills. They will begin formulating expressions from word problems and distinguish their equivalent expressions. After understanding the relationship between the expressions and using the distributive property they will begin solving multistep linear equations in one variable with one solution, infinitely many solutions, or no solution.
